IMPROVEMENT IN SUGAR-CANE MILLS.

Specification forming part of Letters Patent No. 57,883, dated September11, 1866.

To all whom it may concern.-

Be it known that I, ALVAH EATON, of Madison, in the county of Dan andState of Wiscousin, have invented a new and Improved Mill for CrushingSugar-Cane and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable those skilled in theart to make and use proved arrangement of pressure-rollers and a frame,as hereinafter fully shown and described, whereby it is believed thatavery superior mill for the purpose specified is obtained, theadvantages of which will appear or be set forth in the followingdescription.

The frame of the machine is composed of two side pieces, A A, one end ofwhich is connected by joints a a to uprights B, secured to the base 0,on which the device rests. In these side pieces, A A, there are fittedtwo rollers, D D, which are parallel with each other, and have theirbearings or boxes E fitted in pockets F, cast with the side pieces. Thebearings or boxes are prevented from sliding out from the pockets bymeans of keys I), which are driven through the pockets and fit ingrooves in the hearings or boxes, as shown clearly in Fig. 2. By thisarrangement it will be seen that the boxes or bearings of a roller maybe removed and replaced without taking the mill down.

The upper roller, D, has its journals 0 resting in half-boxes f, whichare cast with the side pieces, A A, and serve as supports for saidroller to adjust the other rollers from. The other roller, D, (therebeing three rollers in all,) has its bearings at the inner ends of armsE, which rest on lips g at the front parts of the side pieces, A A. Theouter parts of the .in boxes G, the latter being provided with a rack,2', at their under side, which engage with racks j on the upper ends ofuprights H. By this arrangement the rollers It may be adjusted nearer toor farther from roller D, and the length of the arms E virtuallylengthened or shortened, as occasion may require.

From the above description it will be seen that the weight of the millis made toserve as a means for aiding in giving the pressure to therollers D D", and this pressure modified by adjusting the rollers h, onwhich the outer parts of the arms E rest.

The side pieces, A A, are prevented from rising too high in consequenceof lips k at the outer surfaces of the side pieces coming in contactwith lips I at the upper ends of uprights I, attached to the base 0. Inthese uprights I I a rock-shaft, J, is fitted, having a lever, K, at oneend of it, and two arms, L L, attached in line with the side pieces, AA. By means of these arms L L the frame of the mill is raised when therock-shaft J is turned from right to left. The rock-shaft J is also provided with two projections, m m, to engage with links a 12, attached tothe side pieces, the projections m engaging with the links when theshaft J is turned from leftto right, and drawing down the side pieces, AA, so as to increase the pressure between the rollers D D. By thisarrangement entire control is had over the mill, as regards theregulating of the pressure of the rollers aforesaid.

M is a scraper, which is constructed of aflat piece of steel, or anyother suitable metal which will yield or give to a certain extent. Thisscraper is fitted between the rollers D D, as shown clearly in Fig. 3,and serves as a cane-guide as well as a scraper. The ends of thisscraper are fitted in caps 0 in the sides, A A, of the frame, a squarebeing on each cap for the purpose of receiving a wrench to adjust thescraper, the scraper being provided with screws 19 at its ends, whichscrews pass through the caps, and have nuts 9 at their outer ends.

Having thus described myinvention, Iclaim as new and desire to secure byLetters Patent- 1. The employment or use in a cane-crush- 2 I smsss 3.The adjustable boxes G, in which the rollers h of the arms 'E arefitted, for the purpose of virtually lengthening and shortening saidarms, as specified.

4. The lips 70, at the outer surfaces of the side pieces. A A, inconnection with the lips l, at the upper ends of the uprights I I, asand for the purpose set forth.

ALVAH EATON.
